Altium Releases Altium Designer 6.0

Strengthens Unified Approach to Electronic Product Development

SYDNEY, AUSTRALIA -- (MARKET WIRE) -- November 28, 2005 -- Altium Limited (ASX: ALU), a leading
developer of Windows-based electronics design software, today announced the
release of Altium Designer 6.0, a new and significantly upgraded version of
its groundbreaking unified electronic product development system. Altium
Designer 6.0 strengthens Altium's unified approach to the design by
addressing the challenges posed by the increasing use of programmable
design elements to create smarter products that process data at
ever-increasing speeds.

Altium Designer 6.0 provides a single, unified application that
incorporates all the technologies and capabilities necessary for complete
electronic product development. It integrates board- and FPGA-level system
design, embedded software development for FPGA-based and discrete
processors, and PCB layout, editing and manufacturing within a single
design environment. This, combined with enhanced support for modern design
data, document and project management capabilities, makes Altium Designer
6.0 the first complete solution for electronic product development -- a
solution that caters for both today's and tomorrow's development needs.

"In the development of Altium Designer 6.0 we've taken a strategic approach
to addressing industry trends and the current and future needs of our
customers," commented Nick Martin. "The electronics industry is changing
rapidly in response to demands for smaller, faster and more intelligent
products. We are committed to providing our customers with the capabilities
they need -- not only today, but moving into the future."

With this new release, Altium has strengthened and enhanced almost all
areas of the Altium Designer system. Physical platform design has been
upgraded to support the high board densities and high-speed signaling found
in today's designs. Programmable design support has been extended with
increased programmable device and processor coverage and higher levels of
physical-level integration. And Altium has made it significantly easier to
integrate Altium Designer with company engineering and business management
systems commonly found in medium and large-scale organizations.

Altium Designer is unique in that it recognizes and supports the
convergence of traditionally disparate design disciplines. Creating an
electronic product involves balancing a number of different processes that
must come together to meet business objectives. Projects must be completed
on time and within budget. As electronics products become more intelligent,
designers must become 'smarter' in the way they develop these products in
order to meet these business objectives.

Adding increasing levels of intelligence into electronic products means
large amounts of data must be processed at higher speeds. This presents
significant challenges to designers on both the functional and physical
levels, and forces design constraints to be pushed across traditional
design tool boundaries. Board-level design, programmable logic design and
embedded software development must converge much earlier in the design
cycle in order to deal with increasing complexity and interdependence
between design processes.

Altium believes that system-wide unification of the various design
processes that go to make up a complete electronic product is crucial to
maintaining design efficiency into the future. Altium Designer 6.0 is the
only unified electronic product development solution available that allows
mainstream engineers and designers to take a complete electronic product
from concept to completion within a single, integrated design environment.
